To the side of the kettle or. steam-chamber attached a steamescap'e; tube,"D,-near the t pper end of whichis connected ashort tube or ,opening', which communicates} with: the inte'rior of the steam-chamber-B.- To thetop of his tube D is fitted-a socket,a"h, which reeives the end of a similar steam+escape tube,

D which is attached to andconn'ects'with the upper detachable steam-chamber-"E, near its top, and is provided with azsocket, h This socket receives the end of thesliortfsteam-kscape tube D which is connected to the cover H, and communicates with theinterior of the same through the valve 0, which is held closed against any air, smoke, or: foulf odors arising from within the stove, and entering the lower end of the steam-escape tube D, which opens into the same, after passingthroughthe side "and bottom of the boiler A, as shown in Fig.

2.1This valve 0 in the coverjHmay-be held closed' by a light spring, 1;,- ora weighted valve may be employed, if desiredij This cover H,

with its valve and escape-tube,1nay be placed directly upon the top ofthelower part .or

steam-chamber B when asteam-kettIe of smaller capacity is desired, as shown in Fig.

2, the upper part or steam-chamber E being disconnected from the lowe portion of the utensil. Near the bottom of the steam-chamber E is attached a slide,]3, which may be i moved back and forth in grooves H, secured to the outside of the same by-means of the projection L, which is providedlwith a cavity opening inwardly to receive the 'endof the bar LK, whichpasses through a slotjin-tthe side of the steam-chamber E, which slot is of sufticient length to allow the barjK to move a sufficient distance to operate or open and close the rotary register, composed of twoperforated 'platesor disks, N M, which arepivoted to- .gether at their centers, so as to permit the movement of the bar K, which is s ecured to one of them, to rotate it upon theother one a suflicient distance to open and close the perforation's or openings T through said plates more or less, as may be desired toregulate the amount of steam passing into the upper steamfhal nber E; and in order to keep up a uniform I pressure of steam within each steam-chamber,

" 1 and to gradually check or close its passage to the upperone, and allow it to pass out of the v lower one, tojthe steam-escape tube I), aslide,

R,,L is attached'to the insideof the upper cham jber E directly opposite the slide F, and moving in similar grooves J. This slideR has an opening, through whichthe bar K passes; also,

another opening, P, tapering to a point, which openingfallows the steam to escape to the tube 'D, which communicates with the steam c chamber, 13 at this point. This construction of the tapering opening P in the slide R gradually opens and closes the steam-passage to the tube D at this point correspondingly as the openings T in theregister-plates N Mare closed and opened, so when the register N M is closed 4 -the steam has free escape to the tube 1); thus v allowing articles of foodin the steam-chamber Ejtoibe inspected, put in, or taken out withoutdi'sturbing that in the lower chamber B, a I

perforated disk or plate, W, being placed over 'theregister NM to placethe food upon to be steamed, so as to keep it from interfering with the operation of the register when being moved.
